About
The story so far.
The person behind the work.
James Rixon is the founder and director of Rixon Architecture, a Cambridge practice specialising in retrofit and low-energy design. He set up the practice in 2016 and ran it as a digitally nomadic studio for a period, including a year travelling with his family, before settling in Cambridge (having previously been based in South London).
James focuses on making existing buildings fit for the future, working with homeowners and building owners on phased, low-carbon interventions that improve comfort and cut energy use over time. He has completed Certified Passive House Designer training, is involved in the Architects Climate Action Network (ACAN), and is a co-founder and director of the Cambridge Retrofit Hub, a community benefit society supporting place-based retrofit.
Rixon Architecture is a signatory of the RIBA 2030 Climate Challenge and takes a fabric-first approach to homes and workplaces. Its refurbishment of Clunch House in Cambridge replaced the cement render with breathable insulation and a lime render, and added new double-glazed timber windows.
Rixon Architecture is a separate practice from Rixon Architects in Cirencester.
